VELOClPEDE.

SPECIFICATION forming part of Letters Patent No. 331,113, dated November2%, 1885.

Application filed February 12, 1885. Serial No. 155,734. (No model.)

To all whom it may concern:

Be it known that I, ANTON HEINRICH BOOK, a resident of the city ofMeissen, Kingdom of Saxony, German Empire, have invented a new anduseful Improved Velocipede, of which the following is a specification.

The hereinafter-described improvements relate to velocipedes having twowheels side by side, the characteristic point of this construction beingthat the load on the seat is placed below the center of the axles of thewheels. By this construction easy running of the whole machine is at thesame time insured, and steering is provided for by the application of ahand-brake to one or other of the wheels.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 afront elevation, of such a velocipede, while Figs. 3 to 9 show detailsof construction.

A A are the wheels, constructed in the wellknown manner. Upon the hub ofeach is fixed a brake-disk, a a, covered with indiarubber or leather, orprovided with a wooden rim, if preferred. On the hubs of these wheels AA there are, moreover, fixed drivingdisks b b, likewise covered withsome rough elastic material, such as leather, rubber, or wood. The shaftB is cranked at the center, a, and said wheels A A run loosely thereon.The cranked part c of the shaft B serves as a back for the rider to leanagainst, and maybe suitably cushioned. At 01 d suspension-rods m areprovided upon the shaft B, which carry the pedal-shaft G, and also theseat D, as well as the lever arrangement for operating the hand-brakesand for throwing out of gear the driving bands or belts E.

As already indicated, the pedal-shaft O is loosely held in hearings onthe lower part of the suspension-rods m in such a manner that thesebearings can be moved vertically within certain limits-say twenty toforty millimeters. To this end each of the suspension-rods m is madetubular at its lower end, as shown at 0 in Figs. 2 and 5. The bearing pis guided in this tubular extension 0 of the rod m by means of a roundstud or pivot, q, Fig. 5; and a pin, u, working in slots of the tube 0,prevents lateral rotation of the bearing, and also prevents the latterdropping out. The spiral spring 8 always presses the bearing downward,for a purpose presently to be set forth.

The bearing 19 may be an ordinary divided bearing, or preferably, forthis purpose, an annular bearing engaging by means of a wedge-shaped ribwith a turned recess in the pedal-shaft, so as to reduce friction asmuch as may be. (See Figs. 5 and 9.) Upon the ends of the pedal-shaftare fixed the pulleys m w, constructed similarly to the driving pulleysor disks 1) b, and on which run the drivingbands E E. These may be thinbands of metal belts or belts woven of wire or of textile material; orleather bands may be used, the latter being protected against theinfluence of dampness by well-known means.

As near to the bearings 19 as may be, a recess, y, is turned in thepedal-shaft, Fig. 5. This is embraced by the stirrup-piece 2, so fixedon a stud on the rod J that this rod may be turned therein. If, however,this rod J is pulled directly upward, the pedal-shaft O is also raisedand the tension of the bands E E upon the pulleys b b and 00 00,respectively, so diminished that they slip, and the shaft 0 will notrotateas, for instance, when the velocipede is going down hill andpedaling is not necessary. The said rod J is guided in bearings T, Figs.1 and 4c, in such a manner that it may be raised or lowered as well asturned, the said bearings T being fixed on the suspension-rods. On theupper end of J is provided the handle P, Figs. 1 and 4, which serves forraising and rotating the rod J.

The following arrangement is provided for actuating the brake-band B.The brake-band B is on the one hand fixed to the suspensionrod m by abracket, 1), the other end being hinged to a double lever, W, the latterreceiving motion from a guide-rod, w, engaging with its lower end, Figs.4, 6, and 8. This double lever W is, as will appear from Figs. 2 and 8,so mounted on a bearing in stud Q on the suspension-rod m as to be freeto rotate. To enable this double lever W to be oscillated, therebytightening or loosening the brake-band R, the guide-rod w is, as abovementioned, attached to its lower end. The

which gears a pawl, Figs. 4 and 7, so as automatically to fix the brakewhen the handle P, and thereby rod J, are so rotated that the brake-bandB is tightened.

Ihe manipulation of this velocipede in use may be shortly stated asfollows: After seating himself on the seat D, the rider assumes theposition indicated indotted lines in Fig. 1. On operating thepedal-shaft O the machine is set in motion, and will be steered byputting the brake on one or the other wheel by rotating handle P, andthereby rod J, this causing the machine to describe a curve. When bothbrakes are simultaneously put on, the machine stops, which isadvantageous, as mounting and dismounting are thus facilitated. Therider, moreover, with this construction, need pay no attention tobalance, as is absolutely requisite in older constructions, in

which he is placed above the main shaft, as 20 his center of gravity isplaced below the shaft of the wheels, the load being thus pendulous- 1ysuspended.

I claim- In two-wheeled vclocipedes where wheels 2 5 are placed side byside on one shaft, in combination with the main wheels, the aXle c, therods m, crank-axle O, the vertically-adj ustable and turning rod j,having arm thereon, the rod w, the pivoted lever W, and the brake R, 0as set forth.

In testimony whereof I have hereto set my hand in the presence of twosubscribing witnesses.
